Validation, Verification, and Uncertainty Quantification (VVUQ) in Earth and Space Sciences and Decision Making

Session ID#: 26303

Session Description:
VVUQ is an interdisciplinary research area that seeks to understand and quantify uncertainty flows through computational systems. Validation concerns how well computational outputs represent reality. Verification concerns how well mathematical formulas are represented in computational code. Uncertainty quantification is a set of tools and formalisms for quantifying sources and subsequent flows of uncertainty from all sources that affect the reliability of the output. In Earth and Space sciences this is especially important because outputs are often estimates used to test scientific hypotheses or make decisions that pose risk. This session invites talks from all areas of Earth and Space sciences that describe methods or conclusions from studies of: complex predictive scientific or decision support models; inverse problems including geophysical retrievals; the use of data assimilation as a means of UQ, or the subject of it; and current approaches that informally address VVUQ.
